Connective tissue is the tissue that connects, separates and supports all other types of tissues in the body. Hyaluronic sulfate and chondroitin sulfate are two examples. This tissue is found during the body under the skin and linking organs and other tissues. Connective tissue proper includes loose connective tissue and dense connective tissue. As may be obvious from its name, one of the major functions of connective tissue is to connect tissues and organs. Areolar Connective Tissue Areolar connective tissue A variety of connective tissue consisting of a gel-like matrix combining strands of protein fibers (collagen and elastin) and so cells as fibroblasts, mast cells, macrophages, and fat cells. It is a mixture of glycoproteins, glycoaminoglycans (such as hyaluronic acid), and proteoglycans. Collagen, which is the most abundant protein, constitutes about one-third of all body protein. It is transparent or translucent and viscous in composition; the main chemical components of ground substance are large carbohydrates and proteins known as acid … It consists of cells, fibers & ground substances. If you are on a personal connection, like at home, you can run an anti-virus scan on your device to make sure it is not infected with malware. It consists of a meshwork of collagen, elastic fibres and reticular fibres with many connective tissue cells in between the meshwork of fibres.

Dense connective tissue is reinforced by bundles of fibers … This cell makes the fibers found in nearly all of the connective tissues. Proteoglycans provide the firmness of the ground substance. Connective tissue binds structures together, provides support and protection, fills spaces, produces blood cells, and stores fat.The body uses this stored fat for energy, insulation, and organ protection. Synonym (s): substantia fundamentalis Farlex Partner Medical Dictionary © Farlex 2012 The ground substance of connective tissue is basically composed of [MP PMT 1997] A) Mucopolysaccharides B) Lip… Get the answers you need, now! Pigmented connective tissue is present in the choroid, ciliary body and iris of the eye and dermis of the human skin. Its principal constituents are large carbohydrate molecules or complexes of protein and carbohydrate, called as glycosaminoglycans or mucopolysaccharides (like hyaluronic acid). The material in which the fibers and cells are embedded is called ground substance - a gel composed primarily of glycosaminoglycans (GAGs). It is transparent, colourless, and fills the spaces between fibres and cells. Ground substance Ground substance may be fluid, gel, or solid, and, except for blood, is secreted by the cells of the connective tissue: Cell adhesion proteins hold the connective tissue together. The ground substance includes two major groups: Non-sulfated glycosaminoglycans (hyaluronic acid) The hyaluronic acid consists of long molecule that form a network whose spaces are filled with tissue fluid forming gel-like material. 14. the ground substance & fibers make up the extracellular matrix. Connective tissue extracellular matrix is composed of _____. Powered By Arb4Host Network. See more. Connective tissue is classified into two subtypes which are soft and specialized connective tissue. It fills spaces between organs (Figure 2), for example between the skin and muscles, and surrounds blood vessels, nerves and several organs. Watch this video to find out the specific mechanical property imparted to a connective tissue by its GAGs (3:03) It is composed of proteoglycans and cell adhesion proteins that allow the connective tissue to act as glue for the cells to attach to the matrix. In the central nervous system, the three outer membranes (the meninges) that envelop the brain and spinal cord are composed of connective tissue.
